Further, described windscreen wiper comprises the wiper arm fixing with described gear and the rain shaving blade hinged with described wiper arm, described rain shaving blade comprise windscreen wiper horse and with described windscreen wiper horse detachable be connected scrape slip.
Further, the described windscreen wiper horse back side is provided with hinged ear, described wiper arm front end is provided with two articulated jibs that are set up in parallel, and hinged ear is placed in the hinged groove that described two articulated jibs form and is hinged by a jointed shaft, between described hinged ear and two articulated jibs, adds the rubber pad for vibration damping.
Further, on described windscreen wiper horse, be formed with three be set up in parallel scrape slip groove, described in scrape slip comprise be installed in both sides scrape in slip groove and by elastomeric material, made scrape slip body I and be installed in centre seal bar groove and by super absorbent resin resin material, made scrape slip body II.
Further, described in three, scrape in slip groove, to add to be respectively used to and scrape slip body I and scrape the spring that slip body II provides elastic pressure.
The beneficial effects of the utility model: vehicle wiper of the present utility model, by driven by motor turbine worm, work, the work of worm gear scroll bar makes the connecting rod up-and-down movement being connected with turbine, connecting rod is connected by slide block with tooth bar, thereby make rack drives gear left-right rotation, and then windscreen wiper is swung, the track of windscreen wiper can pass through the initial engagement position control to wheel and rack, replaced the Comlex-locus of four-bar linkage in prior art completely, whole power transmission is simpler, more convenient to operate, and its compact conformation, occupy little space, but also the generation of minimizing wiper noise, improved the traveling comfort of driving.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the utility model structural representation;
Fig. 2 is that Figure 1B-B is to view.
The specific embodiment
Fig. 1 is the utility model structural representation, Fig. 2 is that Figure 1B-B is to view, as shown in the figure: a kind of vehicle wiper of the present embodiment, comprise engine installation, driver train and windscreen wiper, also comprise the tooth bar 1 being in transmission connection with described driver train, described windscreen wiper is by gear 2 and described tooth bar engaged transmission; As shown in the figure, windscreen wiper is provided with two altogether, and the wiper arm lower end of each windscreen wiper is all consolidated with a gear 2, and wheel and rack engaged transmission drives the swing of windscreen wiper by the sway of tooth bar, thereby realizes the object of scraping water.
In the present embodiment, described tooth bar 1 is rigid toothed or flexible rack.
In the present embodiment, described engine installation comprises DC permanent magnet motor 3 and the turbine worm being in transmission connection with described DC permanent magnet motor clutch end; As shown in the figure, scroll bar 4 is in transmission connection with DC permanent magnet motor 3 clutch ends, drives turbine 5 work, and turbine worm structure can play to slow down and increase the effect of turning round, and guarantees the stable output of windscreen wiper operation power.
In the present embodiment, described driver train is slider-rocker mechanism, comprises the rocking bar 6 being in transmission connection with described turbine worm and the slide block 7 being connected with described rocking bar 6, and described slide block 7 is connected with described tooth bar 1; Simple in structure, be easy to realize.
